enCoRe III Functional Overview

The enCoRe III is based on flexible PSoC architecture and is a full-featured, full-speed (12 Mbps) USB part. Configurable analog, digital, and interconnect circuitry enable a high level of integration in a host of consumer, and communication applications.

This architecture allows the user to create customized peripheral configurations that match the requirements of each individual application. Additionally, a fast CPU, Flash program memory, SRAM data memory, and configurable IO are included in both 28-pin SSOP and 56-pin QFN packages.
